The Norma TIPSTRIKE .300 Winchester Magnum 170gr rifle ammunition (Product Code: 20174362) is engineered for medium to large game hunting where immediate energy transfer and decisive stopping power are required. Featuring a polymer-tipped flat-base projectile with a thin front jacket, this cartridge initiates rapid expansion on impact while utilising an internal mechanical lead-lock to secure the lead core to the thicker rear jacket for sustained penetration into vital organs. Factory-loaded into Boxer-primed, reloadable brass casings, this load is packaged in boxes of 20 rounds.

Key Features:

• Polymer TipStrike Projectile: Combines a streamlined polymer tip with a thin forward jacket to deliver high knockdown power and immediate expansion.
• Mechanical Lead-Lock: Anchors the core to the rear jacket wall to prevent separation and maintain penetration depth.
• Reloadable Brass: Loaded in non-corrosive, Boxer-primed virgin brass cases suitable for reloading.
• High Velocity Profile: Tested in a standard 660 mm (26 in) barrel to produce high initial velocity and a flat trajectory out to an optimal zero (MRD) of 194 metres.

Who is the Norma TIPSTRIKE .300 Win Mag 170gr for?

• Deer hunters (Red, Fallow, and Sambar deer) — provides a muzzle energy of 5,069 J and a high G1 ballistic coefficient of 0.454 in a 170-grain .300 Win Mag hunting cartridge, maintaining 3,135 J of energy at 300 metres to ensure rapid expansion and deep vital-zone penetration on large deer.
• Driven wild boar hunters — delivers an initial muzzle velocity of 960 m/s to initiate violent, instantaneous terminal shock on fast-moving game across short-to-medium distances.

Less suitable for: Hunters pursuing very dense, heavy-boned dangerous game requiring maximum weight retention and minimal fragmentation; bonded, heavy-jacketed, or monolithic solid-copper hunting bullets fit heavy bone penetration better. Additionally, this ammunition is strictly incompatible with rifles chambered for .300 WSM, .300 PRC, or .300 Weatherby Magnum.
